Bonnie & Clyde on History, Lifetime, and A&E at 9:00pm ET. Part 2 of 2.

The Great Christmas Light Fight on ABC at 9:00pm ET. Series premiere. As best I can tell, this is a reality series that has grown out of those annual local-interest pieces on the best display of Christmas lights in the viewing area.

Six by Sondheim on HBO at 9:00pm ET. I’d recommend this for those of you who are into Sondheim, but I suspect you’ve already got the date circled and starred. In case you need extra motivation, here’s a full rundown of what’s going to be featured in this documentary.

Sleepy Hollow on Fox at 9:00pm ET.

The Sing-Off on NBC at 9:02pm ET. Two hour fourth season premiere. The episode is title “The Sing-Off is Back!” which, I believe, vastly overestimates the level of enthusiasm your average television viewer has for The Sing-Off.
